Cursor IDE

Describe the Bug

I have noticed that with light use, Cursor consumes a significant amount of CPU resources, even when it is idle. This requires your attention and a fix as soon as possible.

Steps to Reproduce

Start Cursor IDE and observe CPU usage, even without running any tasks or opening files.

Expected Behavior

Cursor IDE should use minimal CPU resources when not actively in use.

No - Cursor works, but with this issue

Hey, it’s possible that some process is excessively consuming your CPU/RAM resources. Could you check which processes are being used while Cursor is running?

Start by checking the built-in Activity Monitor, then use Process Explorer in Cursor itself. There’s also a chance the issue might be related to one or more extensions, so try launching with the flag cursor --disable-extensions. The issue might also be related to the specifics of the project, have you tried checking this in other projects?

It would be great if you could share the info and screenshots of the processes used.
